DRAFT EXPLORATION AND PRODUCTION WASTE RULES REVIEW PACKAGE i
Introduction
Historically, the Division of Oil, Gas, and Mining (DOGM) an agency of the Utah
Department of Natural Resources, provided regulatory oversight of wastes generated
from the exploration and production (E&P) of crude oil and natural gas throughout
Utah. With DOGM’s oversight, these wastes were formerly excluded from the Solid
and Hazardous Waste Act, which is administered by the Division of Waste
Management and Radiation Control (DWMRC), an agency of the Utah Department of
Environmental Quality. However, in 2019, the Utah Legislature made important
changes to the Solid and Hazardous Waste Act in response to a U.S. Environmental
Protection Agency (EPA) requirement for Utah’s solid waste program in the DWMRC
to have primary responsibility for regulatory oversight of E&P wastes under the state’s
Resource Conservation Recovery Act (RCRA) primacy program.
This regulatory shift requires DOGM and DWMRC to coordinate efforts on the primary
objectives which include modifications of existing rules and drafting new rules to clarify
and define each agency’s jurisdiction, and ensure that federal and state program
requirements to protect human health and the environment are met. This review
package was prepared to provide stakeholders an opportunity to participate in an
informal comment process on the draft rules. Comments received during the informal
process will be considered by DWMRC, and appropriate changes may be made
before the proposed rules are presented to the Waste Management and Radiation
Control Board for its formal review and public comment procedure.
Comment Procedure
Comments may be submitted using one of the methods below until the end of the day
on May 3, 2024 as follows:

(9) For both detection monitoring, as described in Subsection R315-308-2(5), and assessment
monitoring, as described in Subsection R315-308-2(12), the Director may specify additional or
fewer sampling and analysis events, no less than annually, depending upon the nature of the
ground water or the waste on a site-specific basis considering:
(a) lithology of the aquifer and unsaturated zone;
(b) hydraulic conductivity of the aquifer and unsaturated zone;
(c) ground water flow rates;
(d) minimum distance between upgradient edge of the landfill unit and downgradient
monitoring well screen (minimum distance of travel); and
(e) resource value of the aquifer.
(10) The owner or operator must determine and report the ground water flow rate and direction in
the upper most aquifer each time the ground water is sampled.
(11) If the owner or operator determines that there is a statistically significant increase over
background in any parameter or constituent at any monitoring well at the compliance point, the
owner or operator must:
(a) within 14 days of the completion of the statistical analysis of the sample results and
within 30 days of the receipt of the sample results, enter the information in the operating record
and notify the Director of this finding in writing. The notification must indicate what parameters or
constituents have shown statistically significant changes; and
(b) immediately resample the ground water in all monitoring wells, both background and
downgradient, or in a subset of wells specified by the Director, and determine:
(i) the concentration of all constituents listed in Section R315-308-4, including additional
constituents that may have been identified in the approved ground water monitoring plan;
(ii) if there is a statistically significant increase over background of any parameter or
constituent in any monitoring well at the compliance point; and
(iii) notify the Director in writing within seven days of the completion of the statistical
analysis of the sample results.
(c) The owner or operator may demonstrate that a source other than the solid waste
disposal facility caused the contamination or that the statistically significant change resulted from
error in sampling, analysis, statistical evaluation, or natural variation in ground water quality. A
report documenting this demonstration must be certified by a qualified ground-water scientist and
approved by the Director and entered in the operating record. If a successful demonstration is
made and documented, the owner or operator may continue monitoring as specified in
Subsection R315-308-2(5)(b).
(12) If, after 90 days, a successful demonstration as stipulated in Subsection R315-308-2(11)(c)
is not made, the owner or operator must initiate the assessment monitoring program required as
follows:
(a) within 14 days of the determination that a successful demonstration is not made, take
one sample from each downgradient well and analyze for all constituents listed as Appendix II in
40 CFR Part 258, 2001 ed., which is adopted and incorporated by reference.
(b) for any constituent detected from Appendix II, 40 CFR Part 258, in the downgradient
wells a minimum of four independent samples from the upgradient and four independent samples

DRAFT EXPLORATION AND PRODUCTION WASTE RULES REVIEW PACKAGAGE Page 33 of 61
from each downgradient well must be collected, analyzed, and statistically evaluated to establish
background concentration levels for the constituents; and
(c) within 14 days of the completion of the statistical analysis of the sample results and
within 30 days of the receipt of the sample results, place a notice in the operation record and
notify the Director in writing identifying the Appendix II, 40 CFR Part 258, constituents and their
concentrations that have been detected as well as background levels. The Director shall
establish a ground water quality protection standard pursuant to Subsection R315-308-2(6) for
any Appendix II, 40 CFR Part 258, constituent detected in the downgradient wells.
(d) The owner or operator shall thereafter resample:
(i) at a minimum, all downgradient wells on a quarterly basis for all constituents in
Section R315-308-4, or the alternative list that may have been approved as part of the permit,
and for those constituents detected from Appendix II, 40 CFR Part 258;
(ii) the downgradient wells on an annual basis for all constituents in Appendix II, 40 CFR
Part 258; and
(iii) statistically analyze the results of all ground water monitoring samples.
(e) The Director may specify additional or fewer constituents depending upon the nature of
the ground water or the waste on a site specific basis considering:
(i) the types, quantities, and concentrations of constituents in wastes managed at the
landfill;
(ii) the mobility, stability, and persistence of waste constituents or their reaction products
in the unsaturated zone beneath the landfill;
(iii) the detectability of indicator parameters, waste constituents, and reaction products in
the ground water; and
(iv) the background concentration or values and coefficients of variation of monitoring
parameters or constituents in the ground water.
(f) If after two consecutive sampling events, the concentrations of all constituents being
analyzed in Subsection R315-308-2(12)(d)(i) are shown to be at or below established background
values, the owner or operator must notify the Director of this finding and may, upon the approval
of the Director, return to the monitoring schedule and constituents as specified in Subsection
R315-308-2(5)(b).
(13) If one or more constituents from Section R315-308-4 or the approved alternative list, or from
those detected from Appendix II, 40 CFR Part 258, are detected at statistically significant levels
above the ground water quality protection standard as established pursuant to Subsection R315-
308-2(6) in any sampling event, the owner or operator must:
(a) within 14 days of the receipt of this finding, place a notice in the operating record
identifying the constituents and concentrations that have exceeded the ground water quality
standard. Within the same time period, the owner or operator must also notify the Director and all
appropriate local governmental and local health officials that the ground water quality standard
has been exceeded;
(b) characterize the nature and extent of the release by installing additional monitoring wells
as necessary;
(c) install at least one additional monitoring well at the facility boundary in the direction of
contaminant migration and sample this well and analyze the sample for the constituents in
Section R315-308-4 or the approved alternative list and the detected constituents from Appendix
II, 40 CFR Part 258; and
(d) notify all persons who own the land or reside on the land that directly overlies any part of
the plume of contamination if contaminants have migrated off-site as indicated by sampling of
wells in accordance with Subsections R315-308-2(13)(b) and (13)(c).
(e) The owner or operator may demonstrate that a source other than the solid waste
disposal facility caused the contamination or that the statistically significant change resulted from
error in sampling, analysis, statistical evaluation, or natural variation in ground water quality. A

DRAFT EXPLORATION AND PRODUCTION WASTE RULES REVIEW PACKAGAGE Page 34 of 61
report documenting this demonstration must be certified by a qualified ground-water scientist and
approved by the Director and entered in the operating record. If a successful demonstration is
made, documented and approved, the owner or operator may continue monitoring as specified in
Subsection R315-308-2(12)(d) or Subsection R315-308-2(12)(e) when applicable.

R315-308-3. Corrective Action Program.
(1) If, within 90 days, a successful demonstration as stated in Subsection R315-308-2(13)(e) is
not made, the owner or operator must:
(a) continue to monitor as required in Subsection R315-308-2(12)(d).
(b) take any interim measures as required by the Director or as necessary to ensure the
protection of human health and the environment; and
(c) assess possible corrective action measures for the current conditions and circumstances
of the disposal facility, addressing at least the following:
(i) the performance, reliability, ease of implementation, and potential impacts of
appropriate potential remedies, including safety impacts, cross-media impacts, and control
exposure to any residual contamination;
(ii) time required to begin and complete the remedy;
(iii) the costs of remedy implementation;
(iv) public health or environmental requirements that may substantially affect
implementation of the remedy; and
(v) prior to the selection of a remedy, discuss the results of the corrective measures
assessment in a public meeting with interested and affected parties.
(d) Based on the results of the corrective measures assessment conducted and the
comments received in the public meeting, the owner or operator must select a remedy which shall
be submitted to the Director.
(i) The corrective action remedy must:
(A) be protective of human health and the environment;
(B) use permanent solutions that are within the capability of best available
technology;
(C) attain the established ground water quality standard;
(D) control the sources of release so as to reduce or eliminate, to the maximum
extent practicable, further releases of contaminants into the environment that may pose a threat
to human health or the environment; and
(E) be approved by the Director.
(ii) Within 14 days after the selection of the remedy the owner or operator must:
(A) amend the corrective action program required by Subsection R315-302-2(2)(e) if
necessary and send a report to the Director for approval describing the selected remedy and
amendments, along with a schedule of implementation and estimated time of completion; and
(B) put in place the financial assurance mechanism as required by Rule R315-309 for
corrective action and notify the Director of the financial assurance mechanism and its effective
date.
(2) Upon approval of the selected corrective action remedy, the Director will notify the owner or
operator of such approval and will require that the corrective action plan proceed according to the
approved schedule.
(a) The Director may also require facility closure if the ground water quality standard is
exceeded and, in addition, may revoke any permit and require reapplication.
(b) The Director or the owner or operator may determine, based on information developed
after implementation of the corrective action plan, that compliance with the requirements of
Subsection R315-308-3(1)(d)(i) of this section are not being achieved through the remedy
selected. In such a case, the owner or operator must implement other methods or techniques,
upon approval by the Director, that could practicably achieve compliance with the requirements.

25 R315-309. Financial Assurance.
R315-309-1. Applicability.
(1) The owner or operator of any solid waste disposal facility [requiring a permit]subject to the
requirements for a permit under Subsection R315-310-1(a), or as otherwise required by the
director, shall establish financial assurance sufficient to assure adequate closure, post-closure
care, and corrective action, if required, of the facility by compliance with one or more financial
assurance mechanisms acceptable to and approved by the Director.
(2) Financial assurance is not required for a solid waste disposal facility that is owned or
operated by the State of Utah or the Federal government.
(3) Existing Facilities.

DRAFT EXPLORATION AND PRODUCTION WASTE RULES REVIEW PACKAGAGE Page 38 of 61
(a) An existing facility shall have the financial assurance mechanism in place and effective
according to the compliance schedule as established for the facility by the Director.
(b) In the case of corrective action, the financial assurance mechanism shall be in place and
effective no later than 120 days after the corrective action remedy has been selected.
(4) A new facility or an existing facility seeking lateral expansion shall have the financial
assurance mechanism in place and effective before the initial receipt of waste at the facility or the
lateral expansion.

R315-309-2. General Requirements.
(1) A financial assurance plan, including the assurance mechanism proposed for use, shall be
submitted:
(a) for new facilities, upon initial permit application; and
(b) for existing facilities, to meet the effective dates specified in Subsection R315-309-1(3).
(2) The financial assurance shall be updated each year as part of the annual report required by
Subsection R315-302-2(4) to adjust for inflation or facility modification that would affect closure or
post-closure care costs. The annual update of the financial assurance shall be reviewed and
must be approved by the Director prior to implementation.
(3) Financial assurance cost estimates shall be based on a third party preforming closure or
post-closure care.
(a) The closure cost estimate shall be based on the most expensive cost to close the largest
area of the disposal facility ever requiring a final cover at any time during the active life in
accordance with the closure plan and at a minimum must contain the following elements if
applicable:
(i) the cost of obtaining, moving, and placing the cover material;
(ii) the cost of final grading of the cover material;
(iii) the cost of moving and placing topsoil on the final cover;
(iv) the cost of fertilizing, seeding, and mulching or other approved method; and
(v) the cost of removing any stored items or materials, buildings, equipment, or other
items or materials not needed at the closed facility.
(b) The post-closure care cost estimate shall be based on the most expensive cost of
completing the post-closure care reasonably expected during the post-closure care period and
must contain the following elements:
(i) ground water monitoring, if required, including number of monitor wells, parameters to
be monitored, frequency of sampling, and cost per sampling;
(ii) leachate monitoring and treatment if necessary;
(iii) gas monitoring and control if required; and
(iv) cover stabilization which will include an estimate of the area and cost for expected
annual work to repair residual settlement, control erosion, or reseed.
(4) Any facility for which financial assurance is required for post-closure care must have a
financial assurance mechanism, which will cover the costs of post-closure care, in effect and
active until the Director determines that the post-closure care is complete.

DRAFT EXPLORATION AND PRODUCTION WASTE RULES REVIEW PACKAGAGE Page 39 of 61
(5) Financial assurance for corrective action shall be required only in cases of known releases of
contaminants from a facility and shall be a current cost estimate for corrective action based on
the most expensive cost of a third party performing the corrective action that may be required.

R315-309-3. General Requirements for Financial Assurance Mechanisms.
(1) Any financial assurance mechanism in place for a solid waste facility:
(a) must be legally valid, binding, and enforceable under Utah and Federal law;
(b) must ensure that funds will be available in a timely fashion when needed; and
(c) any financial assurance mechanism that guarantees payment rather than performance,
but does not allow the Director to approve partial payments to a third party, shall establish a
standby trust at the time the financial assurance mechanism is established.
(i) In the case of a financial assurance mechanism for which the establishment of a
standby trust is required, the standby trust fund shall meet the requirements of Subsections
R315-309-4(1), (2), and (4).
(ii) Payments from the financial assurance mechanism shall be deposited directly into
the standby trust fund and payments from the standby trust fund must be approved by the
Director and the trustee.
(2) The owner or operator of a solid waste facility that is required to provide financial assurance:
(a) shall submit the required documentation of the financial assurance mechanism to the
Director;
(b) prior to the financial assurance mechanism becoming effective and active for a solid
waste facility, the mechanism must be approved by the Director; and
(c) Financial assurance mechanism documents submitted to the Director shall be signed
originals or signed duplicate originals.
(3) The owner or operator of a solid waste facility may establish financial assurance by any
mechanism that meets the requirements of Subsection R315-309-1(1) as approved by the
Director.
(4) The owner or operator of a solid waste facility may establish financial assurance by a
combination of mechanisms that together meet the requirements of Subsection R315-309-1(1) as
approved by the Director. Except for the conditions specified in Subsection R315-309-8(6)(c),
financial assurance mechanisms guaranteeing performance, rather than payment, may not be
combined with other instruments.

R315-309-4. Trust Fund.
(1) The owner or operator of a solid waste facility may establish a trust fund and appoint a trustee
as a financial assurance mechanism. The trust fund and trustee must be with an entity that has
the authority to establish trust funds and act as a trustee and whose operations are regulated and
examined by a Federal or state agency.
(2) The owner or operator shall submit a signed original of the trust agreement to the Director for
approval and shall place a signed original of the trust agreement in the operating record of the
solid waste disposal facility.
(3) Payments into the trust fund must be made annually by the owner or operator according to
the following schedule:

DRAFT EXPLORATION AND PRODUCTION WASTE RULES REVIEW PACKAGAGE Page 40 of 61
(a) for a trust fund for closure and post-closure care, annual payments that will ensure the
availability of sufficient funds within the permit term or the remaining life of the facility, whichever
is shorter for the cost estimates required in Subsection R315-309-2(3). The initial payment into
the trust fund must be made, for a new facility or a lateral expansion of an existing facility, before
the initial receipt of waste and for an existing facility, in accordance with the effective dates
specified in Subsection R315-309-1(3)(a); or
(b) for a trust fund for corrective action, annual payments that will ensure the availability of
sufficient funds within one-half of the estimated length in years of the corrective action program
for the cost estimate required by Subsection R315-309-2(5). Payments shall be determined as
follows:
(i) The first payment shall be at least equal to one-half of the current cost estimate for the
corrective action divided by one-half the estimated length of the corrective action program. The
initial payment into the trust fund shall be made in accordance with the schedule specified in
Subsection R315-309-1(3)(b).
(ii) The amount of subsequent payments must be determined by the following formula:
Next Payment = (RB-CV)/Y where RB is the most recent estimate of the required trust fund
balance for corrective action (i.e., the total cost that will be incurred during the second half of the
corrective action period), CV is the current value of the trust fund, and Y is the number of years
remaining in the pay-in period.
(4) The owner or operator, or other person authorized to conduct closure, post-closure, or
corrective action may request reimbursement from the trustee for closure, post-closure, or
corrective action costs.
(a) Prior to the release of funds by the trustee, the request for reimbursement must be
approved by the Director. The Director shall act upon the reimbursement request within 30 days
of receiving the request.
(b) After receiving approval from the Director, the request for reimbursement may be granted
by the trustee only if sufficient funds are remaining to cover the remaining costs and if justification
and documentation of the costs is placed in the operating record.
(c) The owner or operator shall notify the Director that documentation for the reimbursement
has been placed in the operating record and that the reimbursement has been received.

R315-309-5. Surety Bond Guaranteeing Payment or Performance.
(1) The owner or operator of a solid waste facility may provide a surety bond for a financial
assurance mechanism. The bond must be effective, for a new facility or a lateral expansion of an
existing facility, before the initial receipt of waste or, for an existing facility, in accordance with the
effective dates specified in Subsection R315-309-1(3).
(2) The surety company issuing the bond must, at a minimum, be among those listed as
acceptable sureties on Federal bonds in Circular 570 of the U.S. Department of the Treasury and
the owner or operator must notify the Director that a copy of the bond has been placed in the
operating record.
(3) The penal sum of the bond must be in an amount at least equal to the closure, post-closure,
or corrective action cost estimates of Subsection R315-309-2(3) or Subsection R315-309-2(5),
whichever is applicable.
(4) Under the terms of the bond, the surety will become liable on the bond obligation when the
owner or operator fails to perform as guaranteed by the bond.

DRAFT EXPLORATION AND PRODUCTION WASTE RULES REVIEW PACKAGAGE Page 41 of 61
(a) In the case of a payment bond, the surety shall pay the costs of closure and post-closure
care if the owner or operator fails to complete closure and post-closure care activities.
(b) In the case of a performance bond, the surety shall perform closure and post-closure
care on behalf of the owner or operator if the owner or operator fails to complete closure and
post-closure care activities.
(5) The surety bond guaranteeing payment or performance shall contain provisions preventing
cancellation except under the following conditions:
(a) if the surety sends notice of cancellation by certified mail to the owner or operator and
the Director 120 days in advance of the cancellation date; or
(b) if an alternative financial assurance mechanism has been obtained by the owner or
operator.

R315-309-6. Insurance.
(1) The owner or operator of a solid waste facility may provide insurance as a financial assurance
mechanism. The insurance must be effective, for a new facility or a lateral expansion of an
existing facility, before the initial receipt of waste or, for an existing facility, in accordance with the
effective dates specified in Subsection R315-309-1(3).
(2) At a minimum, the insurer must be licensed to transact the business of insurance, or eligible
to provide insurance as an excess or surplus lines insurer, in one or more states, and the owner
or operator must notify the Director that a copy of the insurance policy has been placed in the
operating record.
(3) The insurance policy must guarantee that funds will be available to close the facility or unit
and provide post-closure care or provide corrective action, if applicable. The policy must also
guarantee that the insurer will be responsible for paying out funds, as directed in writing by the
Director, to the owner or operator or other person authorized to conduct closure, post-closure, or
corrective action, if applicable, up to an amount equal to the face amount of the policy.
(4) The insurance policy must be issued for a face amount at least equal to the closure, post-
closure, or corrective action cost estimates required by Subsection R315-309-2(3) or Subsection
R315-309-2(5), whichever is applicable.
(5) An owner or operator, or other authorized person may receive reimbursements for closure,
post-closure, or corrective action, if applicable, if the remaining value of the policy is sufficient to
cover the remaining costs of the work required and if justification and documentation of the cost is
placed in the operating record. The owner or operator must notify the Director that the
documentation and justification for the reimbursement has been placed in the operating record
and that the reimbursement has been received.
(6) Each policy must contain a provision allowing assignment of the policy to a successor owner
or operator.
(7) The insurance policy must provide that the insurer may not cancel, terminate, or fail to renew
the policy except for failure to pay the premium. If there is a failure to pay the premium, the
insurer may cancel the policy by sending notice of cancellation by certified mail to the owner or
operator and the Director 120 days in advance of cancellation. If the insurer cancels the policy,
the owner or operator must obtain alternate financial assurance.
(8) The insurer shall certify through the use of an insurance endorsement specified by the
Director that the policy issued provides insurance covering closure costs, post-closure costs, or
corrective action costs.

29 R317. Environmental Quality, Water Quality.
R317-6. Ground Water Quality Protection.
6.15 CORRECTIVE ACTION
It is the intent of the Board that the provisions of these rules should be considered when making
decisions under any state or federal superfund action; however, the protection levels are not
intended to be considered as applicable, relevant or appropriate clean-up standards under such
other regulatory programs.

A. Application of R317-6-6.15
1. Generally - R317-6-6.15 shall apply to any person who discharges pollutants into ground
water in violation of Section 19-5-107, or who places or causes to be placed any wastes in a
location where there is probable cause to believe they will cause pollution of ground water in
violation of Section 19-5-107.
2. Corrective Action shall include, except as otherwise provided in R317-6-6.15, preparation
of a Contamination Investigation and preparation and implementation of a Corrective Action Plan.
3. The procedural provisions of R-317-6-6.15 shall not apply to any facility where a
corrective or remedial action for ground water contamination, that the Director determines meets
the substantive standards of this rule, has been initiated under any other state or federal program.
Corrective or remedial action undertaken under the programs specified in Table 2 are considered
to meet the substantive standards of this rule unless otherwise determined by the Director.
TABLE 2
PROGRAM

Leaking Underground Storage Tank, Sections 19-6-401, et seq.

Federal Comprehensive Environmental Response, Compensation and Liability Act, 42 U.S.C.
Sections 9601, et seq.

Hazardous Waste Mitigation Act, Sections 19-6-301 et seq.

Utah Solid and Hazardous Waste Act, Sections 19-6-101 et seq.

B. Notification and Interim Action
1. Notification - A person who spills or discharges any petroleum hydrocarbon or other
substance which may cause pollution of ground waters in violation of Section 19-5-107 shall
notify the Director within 24 hours of the spill or discharge. A written notification shall be
submitted to the Director within five days after the spill or discharge.
2. Interim Actions - A person is encouraged to take immediate, interim action without
following the steps outlined in R317-6-6.15 if such action is required to control a source of
pollutants. Interim action is also encouraged if required to protect public safety, public health and
welfare and the environment, or to prevent further contamination that would result in costlier
clean-up. Such interim actions should include source abatement and control, neutralization, or

DRAFT EXPLORATION AND PRODUCTION WASTE RULES REVIEW PACKAGAGE Page 58 of 61
other actions as appropriate. A person that has taken these actions shall remain subject to R317-
6-6.15 after the interim actions are completed unless he demonstrates that:
a. no pollutants have been discharged into ground water in violation of 19-5-107; and
b. no wastes remain in a location where there is probable cause to believe they will
cause pollution of ground water in violation of 19-5-107, unless, in the case of diesel fuel and oil
releases over 25 gallons, the responsible person demonstrates that the pollutant will not affect
ground water quality by complying with the following:
(1) remove contaminated soil to the extent possible, or to established background
levels, or 500 mg/kg total petroleum hydrocarbons for sensitive areas, or 5000 mg/kg total
petroleum hydrocarbons for non sensitive areas as defined by R317-6-1;
(2) collect soil samples at locations and depths sufficient to document that cleanup
has been achieved or as directed by the local health department;
(3) treat or dispose contaminated soil at a location approved by the local health
department;
(4) submit an interim action report as defined by R317-6-1.23 or as directed by the
local health department.

C. Contamination Investigation and Corrective Action Plan - General
1. The Director may require a person that is subject to R317-6-6.15 to submit for the
Director's approval a Contamination Investigation and Corrective Action Plan, and may require
implementation of an approved Corrective Action Plan. A person subject to this rule who has
been notified that the Director is exercising his or her authority under R317-6-6.15 to require
submission of a Contamination Investigation and Corrective Action Plan, shall, within 30 days of
that notification, submit to the Director a proposed schedule for those submissions, which may
include different deadlines for different elements of the Investigation and Plan. The Director may
accept, reject, or modify the proposed schedule.
2. The Contamination Investigation or the Corrective Action Plan may, in order to meet the
requirements of this Part, incorporate by reference information already provided to the Director in
the Contingency Plan or other document.
3. The requirements for a Contamination Investigation and a Corrective Action Plan specified
in R317-6-6.15.D are comprehensive. The requirements are intended to be applied with flexibility,
and persons subject to this rule are encouraged to contact the Director's staff to assure its
efficient application on a site-specific basis.
4. The Director may waive any or all Contamination Investigation and Corrective Action Plan
requirements where the person subject to this rule demonstrates that the information that would
otherwise be required is not necessary to the Director's evaluation of the Contamination
Investigation or Corrective Action Plan. Requests for waiver shall be submitted to the Director as
part of the Contamination Investigation or Corrective Action Plan, or may be submitted in advance
of those reports.

D. Contamination Investigation and Corrective Action Plan - Requirements
1. Contamination Investigation - The contamination investigation shall include a
characterization of pollution, a characterization of the facility, a data report, and, if the Corrective
Action Plan proposes standards under R317-6-6.15.F.2. or Alternate Corrective Action

assessment.
a. The characterization of pollution shall include a description of:
(1) The amount, form, concentration, toxicity, environmental fate and transport, and
other significant characteristics of substances present, for both ground water contaminants and
any contributing surficial contaminants;
(2) The areal and vertical extent of the contaminant concentration, distribution and
chemical make-up; and
(3) The extent to which contaminant substances have migrated and are expected to
migrate.
b. The characterization of the facility shall include descriptions of:
(1) Contaminant substance mixtures present and media of occurrence;
(2) Hydrogeologic conditions underlying and, upgradient and downgradient of the
facility;

requires. It shall also include a proposed schedule for completion.
3. The Contaminant Investigation and Corrective Action Plan must be performed under the
direction, and bear the seal, of a professional engineer or professional geologist.

E. Approval of the Corrective Action Plan
After public notice in a newspaper in the affected area and a 30-day period for opportunity for
public review and comment, the Director shall issue an order approving, disapproving, or
modifying the proposed Corrective Action Plan. The Director shall consider the following factors
and criteria in making that decision:
1. Completeness and Accuracy of Corrective Action Plan.

DRAFT EXPLORATION AND PRODUCTION WASTE RULES REVIEW PACKAGAGE Page 60 of 61
The Director shall consider the completeness and accuracy of the Corrective Action Plan and of
the information upon which it relies.
2. Action Protective of Public Health and the Environment
a. The Corrective Action shall be protective of the public health and the environment.

(e.g., the transport and disposition of contaminated materials at an off-site facility).
3. Action Meets Concentration Limits
The Corrective Action shall meet Corrective Action Concentration Limits specified in R317-6-
6.15.F, except as provided in R317-6-6.15.G.
4. Action Produces a Permanent Effect
a. The Corrective Action shall produce a permanent effect.
b. If the Corrective Action Plan provides that any potential sources of pollutants are to be
controlled in place, any cap or other method of source control shall be designed so that the
discharge from the source following corrective action achieves ground water quality standards or,
if approved by the Director, alternate corrective action concentration limits (ACACLs). For
purposes of this paragraph, sources of pollutants are controlled "in place" even though they are
moved within the facility boundaries provided that they are not moved to areas with unaffected
ground water.
5. Action May Use Other Additional Measures
The Director may consider whether additional measures should be included in the Plan to better
assure that the criteria and factors specified in R317-6-6.15.E are met. Such measures may
include:
a. Requiring long-term ground water or other monitoring;
b. Providing environmental hazard notices or other security measures;
c. Capping of sources of ground water contamination to avoid infiltration of precipitation;
d. Requiring long-term operation and maintenance of all portions of the Corrective
Action; and
e. Periodic review to determine whether the Corrective Action is protective of public
health and the environment.

F. Corrective Action Concentration Limits
1. Contaminants with specified levels
Corrective Actions shall achieve ground water quality standards or, where applicable, alternate
corrective action concentration limits (ACACLs).
2. Contaminants without specified levels
For contaminants for which no ground water quality standard has been established, the proposed
Corrective Action Plan shall include proposed Corrective Action Concentration Limits. These
levels shall be approved, disapproved or modified by the Director after considering U.S.
Environmental Protection Agency maximum contaminant level goals, health advisories, risk-
based contaminant levels or standards established by other regulatory agencies and other
relevant information.

DRAFT EXPLORATION AND PRODUCTION WASTE RULES REVIEW PACKAGAGE Page 61 of 61
G. Alternate Corrective Action Concentration Limits
An Alternate Corrective Action Concentration Limit that is higher or lower than the Corrective
Action Concentration Limits specified in R317-6-6.15.F may be required as provided in the
following:
1. Higher Alternate Corrective Action Concentration Limits
A person submitting a proposed Corrective Action Plan may request approval by the Director of
an Alternate Corrective Action Concentration Limit higher than the Corrective Action
Concentration Limit specified in R317-6-6.15.F. The proposed limit shall be protective of human
health, and the environment, and shall utilize best available technology. The Corrective Action
Plan shall include the following information in support of this request:
a. The potential for release and migration of any contaminant substances or treatment
residuals that might remain after Corrective Action in concentrations higher than Corrective Action
Concentration Limits;
b. An evaluation of residual risks, in terms of amounts and concentrations of contaminant
substances remaining following implementation of the Corrective Action options evaluated,
including consideration of the persistence, toxicity, mobility, and propensity to bioaccumulate such
contaminants substances and their constituents; and
c. Any other information necessary to determine whether the conditions of R317-6-
6.15.G have been met.
2. Lower Alternate Corrective Action Concentration Limits
The Director may require use of an Alternate Corrective Action Concentration Limit that is lower
than the Corrective Action Concentration Limit specified in R317-6-6.15.F if necessary to protect
human health or the environment. Any person requesting that the Director consider requiring a
lower Alternate Corrective Action Concentration Limit shall provide supporting information as
described in R317-6-6.15.G.3.
3. Protective of human health and the environment
The Alternate Corrective Action Concentration Limit must be protective of human health and the
environment. In making this determination, the Director may consider:
a. Information presented in the Contamination Investigation;
b. Other relevant cleanup or health standards, criteria, or guidance;
c. Relevant and reasonably available scientific information;
d. Any additional information relevant to the protectiveness of a Corrective Action; and
e. The impact of additional proposed measures, such as those described in R317-6-
6.15.E.5.
4. Good cause
An Alternate Corrective Action Concentration Limit shall not be granted without good cause.
a. The Director may consider the factors specified in R317-6-6.15.E in determining
whether there is good cause.
b. The Director may also consider whether the proposed remedy is cost-effective in
determining whether there is good cause. Costs that may be considered include but are not
limited to:
(1) Capital costs;
(2) Operation and maintenance costs;

DRAFT EXPLORATION AND PRODUCTION WASTE RULES REVIEW PACKAGAGE Page 62 of 61
(3) Costs of periodic reviews, where required;
